Configuring and Managing RAID 107
Restrictions and Limitations
The following restrictions and limitations apply to the Replace Member
operation:
• The
Replace Member
functions are restricted to one per array for RAID 0,
RAID 1, and RAID 5, and two per array for RAID 6.
• The
Replace Member
function and rebuild cannot run simultaneously on
a RAID 6 virtual disk. The rebuild operation has a higher priority, and the
Replace Member
operation is aborted if a rebuild begins.
Stopping Background Initialization
Background initialization is the automated operation in which parity is created
and written. BGI does not run on RAID 0 virtual disks. Under certain conditions,
the BIOS Configuration Utility displays a message if you want to stop BGI in
progress. An alert message displays if BGI is in progress and you start any of the
following actions:
• A full initialization on the virtual disk
• A fast initialization on the virtual disk
• A consistency check on the virtual disk
The following alert message displays: The virtual disk is
undergoing a background initialization process. Would
you like to stop the operation and proceed with the
<full initialization/quick initialization/consistency
check> instead?
Click Yes to stop the BGI and start the requested operation or No to allow
the BGI to continue.
